It's very quiet for the amount of cooling it can produce. The rubber pegs were a little difficult to install, but nothing a little bit of lube and needle-nose pliers can't solve. =)

The rubber pegs (some call grommets) and the rubber pads help reduce vibration noise. Though, I think the rubber pegs could be replaced with rubber spacers and screws and it'll essentially behave the same. (maybe even easier installation).

SummaryI owned 4 of the Cougar turbines (1200 rpm, 3-pin) and fell in love with the color and the performance these fans delivered, while keeping my rig quiet. I recently bought the H220 AIO cooler from Swiftech and figured I would upgrade the fans that it came with.

I chose these fans because of the PWM control they offer, and the slightly higher spin speed they have over the other versions of the vortex's. Performance wise these are great, top notch, especially for the price. While gaming, these can keep my CPU under 60 degrees while running my 3570k at 5.0ghz 1.36vcore. My ambient temp is 19 degrees. Now I know there are alot of factors involved with how well my rig cools, and fans are just one of em, but they will be a good choice for your rad no matter your set up.

SummaryI got this to replace the stock fan on an A50 heatsink, which is 3-pin, no PWM, and control fan speed by a resistor cable at fixed speed of 1600 or 2000 rpm. This makes it louder than necessary for me most of the time.

This Cougar is a 4-pin PWM fan which makes use of the mobo speed control according to cpu temps. On my computer at idle it spins at 800-900rpm, at load (prime95) it spins at around 1200rpm. Core temps are always under control: idle around 27C, load around 47C, +/- 2 to 3C. Of course it is not ONLY because of the Cougar fan but instead a combination of heatsink, case fans...etc. The A50 stock fan can cool too but at a higher rpm, therefore louder. With the Cougar I got it cool and quiet.

The orange blades look odd at first sight, but it grew on me. There is a black blade version as well.

The fan blade design and the little black tabs around the frame are supposedly features to control air movement in a centered (columnar) way instead of a dispersed pattern, thus better cooling off the fins on the heatsink. There are videos demonstrating the air flow patterns, quite interesting.

SummaryGreat fans, they cool better then stock H70 fans at full blast, stupid loud they are, these however are near silent full speed. They look amazing, great design. Packaging was very nice.. High quality looking for high quality product, a must buy..

ANTI-VIBRATION PAD DESIGN

AERO-DYNAMICAL DESIGN

HYDRO-DYNAMIC-BEARING TECHNOLOGY

We defined HDB to Hydro Dynamic Bearing. An oil seal design that has a higher reliability and advantage than conventional fan motor design.1. High revolution precision, low vibration noise2. Fluid seal design provide extremely long life span3. Surface tension effect, runs more smoothly with no friction, extremely quietFluid seal design is achieved through the use of oil surface tension and hydrodynamic pumping forces provided by grooves. Bend area is centralized oil and prevented oil leakage out of motor (oil leakage is main problem of sleeve bearing, short life time) . Friction between shaft and HDB will be down due to herringbone structure reaction(friction between the metal is disadvantage of ball bearing, noise & waste heat problem). So HDB conquer sleeve & ball bearing disadvantage to become more reliable & quiet technology for Top-notch fan. Such design concept is successful and applicative on HDD, and we can see a reliability application in it.
